Your washing machine releases hundreds of grams of microplastics a year — a new filter removes 99% of them
Your laundry is shedding more than just lint. Washing machine wastewater is one of the top sources of microplastics, with a single unit in a four-person household producing up to 500 grams a year as synthetic fabrics break down. Those pesky particles — smaller than a grain of rice — make their way into everything from makeup and cleaning products to the food on our plates , eventually winding up in our bodies and posing potential health risks. Now, German scientists have developed a filter that traps nearly all the microplastics escaping our spin cycles, and it takes inspiration from a surprising source: fish. “We took a closer look at the construction of this system and used it as the model for developing a filter that can be used in washing machines,” Dr. Alexander Blanke , one of the lead researchers, said in a press release . These fish have a gill-arch system shaped like a funnel — wide at the mouth and tapering toward the throat. It has comb-like structures ...
